Title: Carbonated beverage dispenser, system and method
Inventor: NOVITSKY CHARLES
IPC: B67D1/00
Filed: 1992-03-05
Granted: 1999-08-24
Abstract: The invention is directed to a carbonated beverage dispenser and to a method of dispensing carbonated beverage.      The dispenser comprises a canister having a side wall, a bottom wall and an open end with a removable lid for closing the open end during operation. A dispensing tube having a puncturing end is provided in the bottom of the canister for puncturing a beverage container loaded into the canister.      The dispensing tube is connected to a flow control valve for controlling dispensing of beverage from the container. Low pressure beverage containers such as plastic or glass bottles and aluminum cans can be used in the dispenser by shaking the canister and container of beverage therein to agitate the carbonated beverage and release dissolved carbon dioxide gas prior to dispensing a serving in order to eventually dispense the entire contents of the beverage container. The dispenser effects a seal with the punctured opening to prevent the carbonated beverage from going flat in the time between the dispensing of different servings.
Patent CA-2063114-C (CA)
Inventor: MCGARRAH ROBERT G
IPC: E03C1/10
Filed: 1992-03-16
Granted: 1999-04-13
Abstract: A backflow valve for use in a post-mix carbonator system for preventing the backflow of carbonated fluid, thereby preventing the contamination of the fresh water supply, and indicating when such a backflow condition has occurred.  In a first embodiment the valve comprises a check seat body which houses an elastomeric valve member, and a sight glass body for viewing the position of the elastomeric valve member.  The valve also comprises top and base connectors for connecting the valve to the fluid carrying line and a shut-off/flush valve for controlling the flow of fluid through the device.  The elastomeric valve member allows the flow of fluid from the supply to the outlet when the fluid pressure at the supply exceeds the pressure at the outlet and prevents the reverse flow of fluid when the pressure at the outlet exceeds the pressure at the supply. As the pressure downstream increases, the elastomeric valve member is forced in the upstream direction over a plurality of steps in the check seat body.  As the elastomeric valve member passes over each step, it engages the step and is thereby prevented from moving downstream.  The position of the elastomeric valve member may be observed through a sight glass body which has a line marking the normal position of the elastomeric valve member.  In a second embodiment the elastomeric valve member is slidably disposed within a retaining chamber that is positioned between the upstream and downstream portions of the valve.  Under normal operating conditions, the elastomeric valve member is in a normal first position allowing fluid flow therethrough; however, in a backflow condition, the elastomeric valve member slides into a second position within the retaining chamber and fluid flow is restricted.  In addition, once the elastomeric valve member is in the second position, it is secured in place and a backflow condition is thereby indicated.

Title: Apparatus for compacting scrap metal
Inventor: CACACE ANTONINO GIORGIO
IPC: B30B15/02
Filed: 1990-09-19
Granted: 2002-09-17
Abstract: Apparatus for compacting swarf to form a billet for subsequent hot working is disclosed. The apparatus includes a die (70) comprising a number of portions (80) defining a cavity (78) for holding a tube in which the swarf is compacted by one or more rams (20). The die portions are surrounded by one or more sleeves (72) which hold them together. The sleeves can be moved in the axial direction to allow the die portions to be separated in the radial direction to release the billet. The sleeves are slidably mount-ed in a housing (74) and are moved apart axially by jacks (108). The outer face of the die and the sleeves are complementally tap-ered to assist release of the sleeves. Charge boxes (16) are provided at each end of the die and swarf is fed from the charge boxes by the rams (20) into both ends of the cavity (78). The die and housing are mounted on a pedestal (116) so as to pivot into axial alignment with mechanisms (118, 120) which grip the ends of the die portions and separate them radially to release the billet. An empty tube can be fed into the die cavity through the mechanism (120) and the billet can be fed through the mechanism (118) af-ter it has been ejected from the die cavity.

Abstract: An improved method for linking images at program activation is provided by use of a symbol vector in a sharable code image. The symbol vector is automatically construted which the linker and operating system use to effect fast loo-kup of symbol values at program activation, thus providing fiexibility similar to that of link-time binding. For each silar-able image being constructed, the programmer provides a list of symbols which are to be made visible outside of the image. These symbols may be procedure names, data cells, absolute values, or any other valid use of a symbolic value. The order of this list must remain fixed from one image build to the next. From this list, the "symbol vector" is constructed (as by the linker) of the value of each of the identified symbols, and the symbol vector is associated with the sharable image. A symbol table is also associated with the sharable image, where each symbol has the value of its index in the symbol vector. When resolving references to other images, the linker does a symbolic lookup in the symbol table of the target im-age and obtains the index into t the target symbol vector. That index is bound into the calling image. Then, at program activation, the image activator uses the index bound into a calling image to obtain the current value of the symbol in the target image.

Abstract: A method of making a porous polymeric material by heating a mixture comprising polyvinylidene fluoride and a solvent system initially comprising a first component that is a latent solvent far polyvinylidene fluoride and a second component that is a non-solvent for polyvinylidene fluoride wherein, at elevated temperature, polyvinylidene fluoride dissolves in the solvent system to provide an optically clear solution. The solution is then rapidly cooled so that non-equilibrium liquid-liquid phase separation takes place to form a continuous polymer rich phase and a continuous polymer lean phase with the two phases being intermingled in the form of bicontinuous matrix of large interfacial area, and cooling is continued until the polymer rich phase solidifies. The polymer lean phase is removed from the solid polymeric material. A porous material so prepared is characterised by a lacey or filamentous structure consisting of a plurality of polymer strands (1) connected together at a number of locations (2) spaced apart along each strand.
